Abstract
BACKGROUND: A phase 3 Radiation Therapy Oncology Group (RTOG) study subset analysis demonstrated improved overall survival (OS) with the addition of stereotactic radiosurgery (SRS) to whole brain radiation therapy (WBRT) in non-small cell lung cancer (NSCLC) patients with 1 to 3 brain metastases. Because temozolomide (TMZ) and erlotinib (ETN) cross the blood-brain barrier and have documented activity in NSCLC, a phase 3 study was designed to test whether these drugs would improve the OS associated with WBRT + SRS.

METHODS AND MATERIALS: NSCLC patients with 1 to 3 brain metastases were randomized to receive WBRT (2.5 Gy × 15 to 37.5 Gy) and SRS alone, versus WBRT + SRS + TMZ (75 mg/m(2)/day × 21 days) or ETN (150 mg/day). ETN (150 mg/day) or TMZ (150-200 mg/m(2)/day × 5 days/month) could be continued for as long as 6 months after WBRT + SRS. The primary endpoint was OS.

RESULTS: After 126 patients were enrolled, the study closed because of accrual limitations. The median survival times (MST) for WBRT + SRS, WBRT + SRS + TMZ, and WBRT + SRS + ETN were qualitatively different (13.4, 6.3, and 6.1 months, respectively), although the differences were not statistically significant. Time to central nervous system progression and performance status at 6 months were better in the WBRT + SRS arm. Grade 3 to 5 toxicity was 11%, 41%, and 49% in arms 1, 2, and 3, respectively (P<.001).

CONCLUSION: The addition of TMZ or ETN to WBRT + SRS in NSCLC patients with 1 to 3 brain metastases did not improve survival and possibly had a deleterious effect. Because the analysis is underpowered, these data suggest but do not prove that increased toxicity was the cause of inferior survival in the drug arms.

这项3期临床结果显示，脑部放疗联合特或者替莫无好处。

家人7月5日发现脑转，现在正在全脑放疗，口服特罗凯，看了老马上面的帖子，心里好纠结啊！

脑转50天，正版特罗凯复查结果：比5月28号稍有减轻，癌胚原3,03降至2,83.说明特有效。继续服用特罗凯，请问老马老师，在脑转的情况下也需要轮换药吗？不是说只有特罗凯入脑吗？下步怎么走，盼指导。这月准备脉冲一下（2,1,0片）不知对否，看到帖子有这样试的，请关注脑转的病人，和家属，有经历的来说说，谢谢!

父74，肺腺癌T2N0MO，12年2月左下肺切除，18外显因子突变，EGFR+++，VEGFR-2 +，HER2 -。13年7月脑出血，确诊为单发脑转。因从未做过放化疗，父亲状态尚好，偶尔头晕健忘。准备上印度易瑞沙。请教老马，是应该先全脑放还是先上靶向？

我们家都放过了，联合了特，联合替。效果未知。纠结的方案，现在不敢再用替了，感觉我们家每次用替都有不好的反应。

我们家EGFR基因没有突变，免疫组化VEGF HER ALK也全部是阴性，2012年10月24日开始第一次化疗培美+奈达铂，一共化疗了6次+单药培美一次。于2013年4月22日结束化疗（这时医生发现培美耐药了），8月7日增强核磁发现脑转多发（目前脑转没有症状），现在医生建议脑部全放。请大家指点现在是不是脑部全放的最佳时候，全放后化疗用什么方案较好。恳请各位帮我出出主意。
